如果我们要到一对主从表增加级联删除，则要在主表中的引用属性上增加Required关键字，如：

public class Destination
{
public int DestinationId { get; set; }
public string Name { get; set; }
public string Country { get; set; }
public string Description { get; set; }
public byte[] Photo { get; set; }
public List<Lodging> Lodgings { get; set; }
} public class Lodging
{
public int LodgingId { get; set; }
public string Name { get; set; }
public string Owner { get; set; }
public bool IsResort { get; set; }
public decimal MilesFromNearestAirport { get; set; }
[Required]
public Destination Destination { get; set; }
}
